.Beferring to the drawings in detail whereinsertion of thecartridge in the gun vor re 7 in like characters of reference denote corceptacle, the annular member is. forced outresponding parts, the invention as shown ward so that the flange 19 engages behind the comprises a cylindrical container 10 which offset portion 18 of the closure cap 16. This 40 may he formed of any suitable material, gpontion of the'closure cap is thus spread or such as metal, either stiff or pliable. This forced outwardly from the container 20 so container is provided at one end with an as to relieve frictional engagement between outwardly disposed flange 11 which extends the closure cap andeontainer and permit .of

circumferentially, and this end of the con the ready removal of the cap. The container 45 tainer is closed by a closure cap 12. It will is then inserted within the barrel .orrecepbe understood that theflange 11 may be used atacle 21. As the container is torced inward, as a means to permit gripping .by or .conthe outwardly offset portion 15 .of the cap 12 tact with an extracting device. The cap is engages the adjacent end of the receptacle provided with a crimped flange 13, the free 21, so an the latter acts to spread the flange,

.50 edge of which extends longitudinally .and of the closure cap 12 outward anddisenthe invention what is like comprising a tubular container open at,

each end, a removable closure for one end of the container, means providing a triotional engagement between said closure and container, an offset flange extending around the periphery of the closure and spaced from the container for engagement by a spreader element, a removable closure for the opposite end of the container, and means comprising a slidable ring carried by the container between the ends thereof and movable into engagement with said firstnamed closure and adapted to disengage the same.

2. A cartridge forgrease guns and the like comprising a tubular container open at each end, a removable closure for one end of the container, means providing a frictional engagement between said closure and container,
